GroupI (GI) self-splicing ribozymes are attractive tools for biotechnology and synthetic biology. Several trans-splicing and related reactions based on GI ribozymes have been developed for the purpose of recombining their target mRNA sequences. By combining trans-splicing systems with rational modular engineering of GI ribozymes it was possible to achieve more complex editing of target RNA sequences. In this study we have developed a cooperative trans-splicing system through rational modular engineering with use of dimeric GI ribozymes derived from the Tetrahymena groupI intron ribozyme. The resulting pairs of ribozymes exhibited catalytic activity depending on their selective dimerization. Rational modular redesign as performed in this study would facilitate the development of sophisticated regulation of double or multiple trans-splicing reactions in a cooperative manner.
